The Claim

Five gut bacterial genera—Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister—collectively mediate 14.50% to 18.66% of the association between dietary animal protein intake and bone mineral density at three skeletal sites in Chinese adults.

How it works
1 study reviewed
In plain English

In Chinese adults, the gut bacteria Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister account for 14.50% to 18.66% of the link between eating animal protein and bone mineral density at three bone sites.

See the scientific wording

Five gut bacterial genera—Lactococcus, Lactonifactor, Lachnoclostridium, Coprococcus_1, and Dialister—collectively mediate 14.50% to 18.66% of the association between dietary animal protein intake and bone mineral density at three skeletal sites in Chinese adults, suggesting a partial microbial pathway in this relationship.

Why this might work

Eating more animal protein changes the types of bacteria in the gut, and these bacteria produce chemicals that alter how much calcium the body absorbs and how much inflammation is present, which directly affects how much bone is built or broken down.

  1. Study: Gut microbiota mediated the curvilinear association between dietary animal protein intake and bone mineral density in Chinese adults.

    This study found that five types of gut bacteria explain about 15–19% of why eating more animal protein might help or hurt bone density in Chinese adults — meaning these bacteria are part of how diet affects bones.
